Здравствуйте!
Задумал использовать таблицу с многоуровневым заголовком, но вот беда, если заголовок формировать при запуске приложения, все отображается как надо:

Собственно вот так вызывается формирование многоуровневого заголовка для таблицы
1.
header = new GroupTableHeader(jTable1);
а вот сам GroupTableHeader
